ORE-SAMPLING MACHINE.

SPECIFICATION forming part of Letters Patent No, 299,920, dated June 3, 1884.

Application filed February 2. 1E 84. (No model.)

To ctZZ whom; it may concern.-

Be it known that I, THOMAS T. Evan, a citizen of the United States, residing at Decatur, in the county of Summit and State of Colorado, have invented certain new and useful Improvements in Ore-Sampling Machines, of which the following is a description.

This invention relates to that class of devices used to divide a quantity of comminuted ore into a certain number of equal parts; and it has for its object to provide means whereby a quantity of ores, earths, chemicals, seeds, 820., may be divided into a number of equal parts automatically and rapidly;

To this end my invention consists in a hopper or receptacle having a hole in its bottom for the ore to discharge from, means for stirring or distributing the ore, and means for dividing it while running, as hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of my inven tion; and Fig. 2 is a side elevation of the same, part in section.

13 represents a hopper, which is to receive theore or other material to be separated. This hopper is supported on stanchions E.

G is a bar secured across the top of the hopper, to support the pipe or sleeve F, which depends therefrom into the center of the hopper-outlet, and extends to the lower edge of the hopper, for the purpose of preventing the ore from coming against the central shaft, A. This shaft is journaled near its top in the crossbar G, and is cupped at its bottom to receive and rotate upon a stud, H.

I is a screw or spiral blade, like an anger, firmly secured to shaft A.

C is a cylindrical casing around and secured to said screw, to revolve with it and the shaft A.

D is the divider, consisting of a cone grooved from its apex to its base into ridges, like a partly-closed fan, the ridges between the grooves being equidistant apart and corresponding in number to the number of parts into which the ore is to be divided. Upon the apex of this divider the stud H is mounted, so that the cylinder 0 is centrally over the divider, and the axis of the cone coincides with 5o a downward-extended axis of the cylinder. This cylinder may be rotated by power applied through the beveled gear-wheel J or otherwise; but I find that the descending of the ore through the screw-thread rotates the cylinder enough for practical purposes. The ore or other material placed in the hopper is discharged therefrom through the cylinder 0, causing the same to rotate, as described, thereby delivering the contents equally at all sides 6 upon the divider, whose equal grooves divide the same into equal quantities, which may be received in suitable receptacles, K, placed below the spout end of one or more grooves. A similar smaller ore-sampling machine might 6 be placed below one or more of said grooves, thus subdividing the ore to any degree desired. If the first and second samplers each had twelve grooves, then each division from the second would represent a one hundred 0 and forty-fourth part of the whole.

The whole machine may be mounted on legs or on casters, or both, as circumstances may require. The lower ends of the stanchions E are secured upon the divider D, to insure the hopper and divider remaining central with each other.

The sample from the grooves can be all collected into one chute or false bottom and sent to any desired place.

,What I claim as my invention, and wish to secure by Letters Patent, is

The combination,with a hopper, of the conical grooved divider described, and a cylinder having a screw-thread, and a vertical shaft j ournaled to rotate in the said hopper upon the apex of said divider, substantially as and for the purpose specified.
